How to Spell “sum”

Children most often write this word as soom, usm, summ, suum. Those errors are useful — each one points to a specific sound the child has not yet connected to a letter.

1. Start with the picture: <strong>sum</strong> begins with the /s/ sound, so begin with "s".
2. Say the word slowly three times, then write one sound per letter: <strong>s - u - m</strong>.
3. The "u" in <strong>sum</strong> says /ʌ/, not the letter name "uh". The mouth stays relaxed.
4. Blend the last two sounds smoothly: <strong>su</strong> + <strong>m</strong> = <strong>sum</strong>.

Phonics Tip for Sum

"sum" and "gum" and "hum" share the ending /ʌm/. Say them back to back so the child hears that only the first sound changes. That is the core of the -um family.

Fun Facts About Sum

It belongs to the -um family, which has 3 other words in it: gum, hum, mum.
